SAT Subject Test - Physics

Hi, I am aiming for a perfect score in the SAT Subject Test Physics this year. I am probably going to take it on the May test date. I am currently taking AP Physics 1 right now. That’s the only physics class I have ever been in. Is it good for a perfect score on the SAT Phsyics Test plus some extra studying. Also, how hard is it to get a perfect score on that test? Do a lot of people get a perfect score on it?
